SAM A. WILLSON, OF RUSIQTEXAS.

HORSE-DETACHER.

sPEciFIcA'rroN forming part of Letters Patent No. 272,394,01ated-February 13, 188e.

Application filed November 10, 1882, (No model.)

To all whom it may concern:

Beit known that I, SAM A. WILLsoN, a citil zen of the United States, residingat Rusk, in

the county of Cherokee and State ot' Texas, have invented certain new and useful Improvements in Devices for Detaching Horses and other Animals from Vehicles, ot' which the following is a specication; reference being hady therein tothe accompanying drawings.

My invention relates to horse-detaching de-v vices, the object being to provide a device of this character of simple, inexpensive, and durable construction, and adapted to readilydisengage the traces from the single-tree.

The invention consists in the improved construction and combination of partshereinafter t'nlly described, and pointed out in the claim.

In the drawings, Figure l represents a plan View of a sin glo-tree provided with my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view of the end of the whiftletree.

A represents a single-tree pivotally secured in the usual manner tothe cross-bar B ot' the Y shafts. l

C represents a loop secured to the upper side ot' the single-treeand at lits opposite end to the under side ot' the cross-bar B to limit the movement of the single-tree. The singlev tree is provided with the usual spindle or pins, a a, toreeeive the ends ot' the traces.

C. U4 represent sliding detaching-bars, the

' outer ends of which-are bent at right angles to'bear against the ends of the spindles a a to securely retain the traces upon the spindles.

D D represent collars secured to or formed integral with the detaching-bars G' C', and arranged upon the latter adjacent to their outer angles, so that the collars will surround the outer ends of 4the single-tree when the traces are attached, and adapted, when the bars C C are operated, to disengage the traces from the single-tree. Thebarstl C are guided upon the upper side of the single-tree by staples or keepers c c, and the' inner ends ot' said bars form opposite right angles G2 G2. y

E represents a bell-crank lever fulcrumed upon the upper side of the single-tree, and having Vtheinner ends ot the sliding bars C C pivotally secured thereto, as shown. To the forward arm ot' the lever E is secured one end of a spiral spring, e, the opposite en d ot' said spring being secured to the single-tree.l

The rear arm of the lever is providedwith a perforation, E', to receivea cord adapted `to be arranged in easy reach of the driver. The spring e operates to retain the sliding bars C C in position, as shown in Fig. 1.

To disengage the trace trom the single-tree it is only necessary to operate the lever E,-

which forces thesliding bar outward thus disengaging the traces.

In connection with my improved device I employ upon the shafts, instead otl the usual holdback-strap, open-ended loops or bent bars F F, lwhich allow the holdback-strapsto freely slip o'.

I claim- The combination, with a single-tree, ot two sliding detaching-bars arran ged in guides upon the single-tree, and'provided at their outer ends with collars and trace-retainermwhile Vtheir inner ends are bent to form opposite angles, and are pivoted to a lever, E, a spiral spring, e, secured at one end to said lever, and at the oppositeend to the sin gle-tree, to lie parallel with the latter, and a loop, @substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

- SAM A. WILLSON.
